โœฆ Synopsis

Shock

layer theory is extended to the nonequilibrium exchange system with axial dispersion. A moving coordinate scheme enables us to establish the existence condition and the uniqueness of the shock layer. In addition to the strategy for the numerical determination of the shock layer, an approximate solution is discussed which neglects the coupled effect of the dispersion and the mass transfer resistance. This solution provides a basis for the quantitative analysis of the shock layer thickness and the departure from equilibrium. Applications are illustrated by using the Langmuir isotherm and a numerical solution of the transient equation confirms the usefulness of the shock layer theory.

This paper describes a new numerical study of the flat plate shock/boundary-layer interaction by using a weighted high-resolution, total variation diminishing (TVD) scheme. The key difference of this study from former studies is that new secondary vortices in the separated region have been found for
